Flexible realtime timestretching and pitchshifting with a granular engine in Max/MSP.

With this external you can expand your max toolkit for natural and experimental playback. It incorporates the algorithm used by Mattijs Kneppers in his granular stretcher patch and adds a load of extra options and features.

It is available for both windows and mac, and works in max 5 (in 32bit) and max 6 (in 64 bit).

The video below gives you an impression of what you can do with it by giving you a walkthrough using the helpfile:

hi there,
great external, love it.

but, does anyone now a way to be able to select start and end points of a loop (using grainstretch~ for playback), and change them at any time? Would like to be able to do that with waveform~ if poss.?

excuse me if this is a dense question, but it says it works in max 64bit. however there is no 64bit external included in the zip file and thus max will not recognize the file. can someone clue me in here? thanks!
